IPC: F16G3/02
Filed: 1994-07-21
Abstract: PURPOSE:To easily connect both ends of a belt to each other and enable assembling of the fabric belt to a machine by alternatively combining loops formed on both ends of the belt, and connecting them by means of a connection pin made of high strength fiber. CONSTITUTION:A belt 1 is composed of transverse yarns 2 made of high strength fiber and extending widthwise, and longitudinal yarns 3 made of high strength fiber and extending in a longitudinal direction. Loops 4, 5 composed of the longitudinal yarns 3 are formed on both ends of the belt with spacing widthwise. High molecular material, etc., is impregnated and then hardening is performed. A connection pin 7 is prepared by bundling a plurality of high strength fiber yarns, and spirally winding yarn therearound, forming a projection 8, and then performing hardening. The pin 7 is penetrated through the loops 4, 5 formed on both ends of the belt. At this, time, the pin 7 is easily penetrated while being rotated due to the spiral projection 8. The belt is widely adopted to machines on which it is difficult to mount metal such as metal finder, and connection is carried out with a simple operation.

Title: Actual-photographic picture and three-dimensional model composing device
Inventor: FUKUDA YOSHIFUMI
IPC: G03B35/00
Filed: 1995-07-05
Abstract: PROBLEM TO BE SOLVED: To control two displays or a composed display so that the correspondence relation of an actual-photographic picture and a three-dimensional model can easily be grasped by detecting the matching state of the two pictures at the time of displaying the actual-photographic picture and a three-dimensional computer graphic picture in an actual-photographic picture/three-dimensional model composing device. SOLUTION: When a matching state detection part 110 receives the viewpoint parameter of the actual-photographic picture and the viewpoint parameter of the three-dimensional computer graphic picture, the part 10 calculates the matching state, and composes the two pictures when matching is detected. Thus, the correspondence of the actual-photographic picture and the three- dimensional model can easily be grapsed.

Title: Semiconductor laser device
Inventor: KAKIMOTO SHIYOUICHI
IPC: H01S5/023
Filed: 1983-09-12
Abstract: PURPOSE:To stabilize the output of a laser by increasing the photocurrent output of a photodiode which forms a returning path and decreasing the irregularity of the output value. CONSTITUTION:The upper surface of a base 5 is divided into a horizontal upper surface 6 and an obliquely cut oblique surface 8, and a laser chip 1 is soldered to the surface 6. The length of the surface 6 is formed to substantially coincide with that of the chip 1, and the surface 8 is formed bliquely at 45 deg. to the side which does not shield the laser light emitted from the rear surface 3 of the chip 1 to the surface 6. Even if the expanding angle of the laser light obliquely emitted from the chip 1 is large, it is approx. 50 deg. and the expanding angle to one side is 25 deg.. For example, when the surface 8 is inclined at 45 deg. to the surface 6, the laser light emitted from the surface 3 is emitted to the photodiode 4 side almost without reflecting or scattering. Accordingly, the laser light emitted from the rear surface 3 is emitted effieicntly to the photodiode 4, thereby obtaining large photocurrent output.

Title: Multilayer interconnection board
Inventor: KONO TAKESHI
IPC: H05K3/46
Filed: 1987-07-07
Abstract: PURPOSE:To improve signal transfer efficiency by forming interlayer grounding conductors adjacent to an interlayer signal connecting wire for a multilayer printed interconnection board selectively arranging the interlayer grounding conductors and matching characteristic impedance. CONSTITUTION:The smaller a space D between a signal connecting wire 1 and a grounding conductor 2 is, the smaller the characteristic impedance of the signal connecting wire becomes. When a plurality of the grounding conductors 2 are disposed to one signal connecting wire, characteristic impedance can further be reduced. The positions of the connecting conductors for a multilayer printed interconnection board are arranged normally at lattice points, and the shapes and wire diameters of the connecting conductors are equalized both in signal conductors and the grounding conductors. Consequently, since the arrangement of the connecting wires is normalized at the lattice points and length in interlayer length, the grounding conductor 2 for shaping the characteristic impedance of the required signal connecting wire 1 can easily be determined only by indexing a pattern when the characteristic impedance of the signal connecting wire is computed previously by a patterned model. Accordingly, the characteristic impedance of the signal conductor can be matched on the layer and between the layers, thus forming the interconnection board having excellent transfer efficiency.

Abstract: PURPOSE:To obtain an iron base high C, high Cr, high Fe type martensite cold working tool steel that is excellent in abrasion resistance and high in toughness, by incorporating C, Cr, V, Mo, Si and Mn in a prescribed proportion. CONSTITUTION:The high abrasion resistant and highly tough cold working tool steel consists of 2.0-4.0wt% C, 7.0-17.1wt% Cr, 6.0-14.0wt% V, 0.5-3.0wt% Mo, 2.0wt% or less Mn and the balance of Fe and impurities.

Further, the carbon and the carbide forming elements are suitably kept balanced on the one hand to improve the abrasion resistance greatly and on the other hand to minimize the lowering of the toughness.
